Question

The genotype of a plant showing the dominant phenotype can be determined by __________​

Answer 1

Answer:

test cross

Explanation:

• The genotype of a plant showing a dominant genotype can be determined by a test cross.
• A test cross is a cross between the progeny exhibiting dominant character and the recessive parent.
• The progeny exhibiting dominant character could be homozygous or heterozygous. This could be differentiated with the help of the test cross.
• In the test cross, if the cross produces all dominant offsprings, then the genotype of the progeny in question is homozygous dominant.
• If the cross produces dominant and recessive offsprings in the ratio 1:1, then the genotype of the progeny in question is heterozygous dominant.
